Electric bed frame

Abstract

An electric bed frame, including a frame body, an electric support plate, a driving device, and bed legs detachably connected to the frame body. The frame body includes a first base frame and a second base frame, the electric support plate includes a first electric support plate connected to the first base frame, and a second electric support plate connected to the second base frame, the first base frame and the first electric support plate form a first folding unit, and the second base frame and the second electric support plate form a second folding unit; the first folding unit and the second folding unit are rotatably connected by a rotation mechanism, and when being rotated to an extreme position, the first folding unit and the second folding unit are parallel, and the driving device is positioned between the first folding unit and the second folding unit.

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application is based on and claims the priority benefits of China application No. 202121054734.X, filed on May 17, 2021. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUNDTechnical Field[0002]The present application relates to the field of an electric bed frame, and more particularly to electric folding bed frames.Description of Related Art[0003]During logistics transportation, the larger the cargo, the higher the freight. Especially in developed countries with higher labor cost, the freight does not rise uniformly with the sizes of the cargo, but increases in a stepwise manner. Once the size of the cargo is higher than a certain threshold value, the freight is greatly increased even if the size exceeds a little.

AI Technical Summary

Benefits of technology

This patent design reduces the cost of transporting a bed frame by folding the first and second folking units. It also reduces noise and the power required for lifting the back support plate, and reduces the overall size during transportation. This is achieved by improving the design of the roller and first support rod to make lifting quieter and using a receiving groove to partially receive the driving device, reducing the space between the first and second folding units.

Problems solved by technology

Especially in developed countries with higher labor cost, the freight does not rise uniformly with the sizes of the cargo, but increases in a stepwise manner.

If the cargo is too large, the cargo is even rejected, logistics distribution cannot be performed.

However, the electric bed frame is much more complex than a common bed frame in structure and has the function of adjusting the angles of a plurality of bed plates.

If the electric bed frame is also disassembled for transportation, since there are too many electrical components and mechanical structures on the electric bed frame, on the one hand, the assembly difficulty of the buyer is large, and on the other hand, it is difficult to guarantee the use stability after assembly.

Therefore, it is difficult to transport by using a disassembly transportation method.

Regarding the related art described above, the inventors believe that there exist defects that the electric bed frame is excessively large and the transportation cost is excessively high.

However, if there is no extension rod, the driving rod needs to be rotatably connected to the linkage rod, and in order to obtain the inclination angle, only the cylinder block portion of the first driving cylinder can be uplifted in a direction away from the back support plate, and the overall volume of has to be increased, which makes it difficult to achieve the purpose of reducing the volume and the transportation cost.
